'This invention relates to certain vnew and useful improvements in boxlock.V

` The primary object of the invention is to provide a lock embodyinga'hasp and a keep- 7 er and in which the keeper forms part of the lockmechanism for' the box, the keeper for the hasp being displaceable byreleasing part of the lock mechanism through the action of a key to`expose another' key receiving '1U opening for the reception of the samekey to release the main bolt of the lock and Vpermit opening movement ofthe box cover.

' 'With the above and other objects in view that will become apparent asthe nature oi 15 the invention is better understood, the same consistsin the novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawings and claimed.

Figure 11 is a sioned latch and Figure 12 is a side elevational view ofthe key employed V:tor releasing the lock mechamsm.

Referring more in detail to the accompanying drawings, there isillustrated a lock box perspective viewoi the tenplate for the shacklekeeper;

having a front wall 1, a bottom wall, end k walls, a rear wallrand acover2 hinged to the rear wall as at 3 and carrying corner blocks 4tcorrectly to locate the cover on the box body when in closed position;The free edge of the hinged cover 2 carries a swinging hasp 5 receivedon a keeper 6 that is in the form of a U-shaped shackle associated withthe front wall 1 of the box and with which a padlock 7 or otherretainingmeans may be associated, the main lock for the box, however, beinglocated interiorly thereof.

The lock mechanism within the box is mounted upon a plate 8 secured tothe inner side or the front wall 1 of the box adjacent its upper edge,the plate having right angularly directed walls 10 and 11, the plate 11intermediate its upper and lower edges carrying an angularly directedarm 12 parallel with the plate 8` The shackle keeper 6 comprises a longleg 13 and a short leg 14, the long leg 13 of the keeper shackleextending through registering openings in the front wall 1 of the boxand the plate 8 and through an opening in the arm 12 while the shortleg,r 14 of the keeper shackle extends through openings in the frontwall of the plate and projects into a barrel 15 as shown in Figure l0carried by the inner sides of the plate 8. A coil spring 16V surroundsthe long leg of the keeper shackle between the plate 8 and nl o abutment17 on said leg, for normally iniuencing the keeper shackle in adirection inwardly of the box.

The keeper shackle is normally locked within the box by means of atensioned latch 18 slidably mounted between guides 19 on the plate 8, 'alinger 2O of the latch 18 being engaged in a side notch 21 formed in theshort leglt of the keeper shackle. One end of the latch 18 carries anangle flange 22 having an opening 23 therein to receive one end of acoil spring 24, the other end of the coil spring being attached to theangle Wall 10 on the plate 8 for normally iniiuencing the latch 18 in adirection toward the short leg of the keeper shackle. `The end of thelatch 18 opposite the angle end 22 is provided with a lateral flange 25having upstanding abutments 26.

The key for operating the lock mechanism is shown in Figure 12 andcomprising a sha nk 27 having an angle Ward 28 at one end, a collar 29intermediate its ends to limit projecting movement of the key into thelock and a handle 30 upon its other end. To release the finger 20 of thelatch 18 from the notch in the side of the short leg of the keepershackle, the key 27 is inserted through the opening 31 in the front Wallof the box to be positioned between the abutment 26, it being understoodthat the side of the barrel 15 is slotted as at 15a to accommodate thepassage thereinto of the linger 2O for engagement With the shackle leg.The key 27 is then turned to engage the abutment 26 adjacent the latch18 and to shift the latch against the tension of the spring 16 and atwhich time, a pull upon the latch keeper 6 Will move the short leg 14thereof outwardlyof the box and expose a key receiving opening 32.Return sliding movement of the latch 18 under influence of the spring 24is limited by the end abutment 26 enga ging the angle end wall 11 of theplate 8 for also limiting projecting movement of the latch finger 20into the barrel 15.

The locking bolt for the hinged cover 2 is in the form of a U-shaped rodcomprising a bolt 33 and a guide rod 341 connected at adjacent ends bythe cross rod 35, the bolt 33 and rod 311 being slidable throughopenings in the angle walls 10 and 11 of the plate 8 with the cross rod3'5 positioned outwardly of the Wall 1(). 'lhe end of the bolt 33projecting through the end Wall 1-1 is adapted for engagement Vith akeeper` 36 depending from the hinged cover 2. The bolt frame is normallytensioned in a direction of movement for latching engagement with thekeeper 3G by the coil 'spring 37 having one end extended through the endWall 10 of the plate 8 and engaged 'with the cross rod 35 of the boltfram?, as shown at 38, While the other end of the f paring is er ragedwith the linger 39 projecting outwardly from the plate 8 as shown inseveral of the figures.

lVith the latch finger 2O disengaged from the side notch in the shortleg lll of the keep er shackle G and said short leg removed from the boxand displaced laterally of the key receiving opening 32, the key shownin Figure 12 is then inserted in the opening 32 for passage through thebarrel 15, the side of the barrel being slotted as at 4() to accommodatethe passage of the key ward 28 as shown in Figure 7. The Ward 28 of thekey is then located in engagement With the lug 41 projecting laterallyfrom the guide rod 34 and upon rotation of the key 27, the guide rod,together with the bolt 33 are shifted against the tension of the spring37 to disengage the bolt 33 from the keeper 36 as shown in Figure 7 andat which time the cover 2 of the box may be opened upon its hingedmounting. Movement of the bolt frame against the tension of the spring37 is controlled by the stop 42 upon the end of the guide rod 34 thatmoves into engagement with the end Wall of the plate 8.

From the above detailed description of the invention, it is believedthat the construction and operation thereof will at once be apparent, itbeing noted that the padlock 7 engaged with the keeper shackle 6 asshown in Figure 1 is foreign to the particular lock mechanism formingthe basis of this application, except that the hasp 5 overlies the keyreceiving opening 31 WhichV permits operation of the sliding latch 18.It is necessary to release the sliding latch from engagement With theshort leg of the keeper shackle in order topermit the short leg to beremoved from the key receiving opening 32 and throuoh which opening thekey for operating t e bolt 33 is passed, and while there is herein shownand described the preferred embodiment of the invention, it isnevertheless to be understood that minor changes may be made thereinwithout departing from the spirit and scope of the invention as claimed.
